ADVERTISING DEVICE.

Application filed May 22, 1923. Serial No. $10,766.

To all 10720171 it may concern.-

Be it known that I, Hnnnnirr HANsooM, a citizen of the United States, residing at Fryeburg, in the county of Oxford and State of Maine, have invented certain new and useful Improvements in Advertising Devices, of which the following is a specification.

My invention relates to advertising devices of that class in which display cards or the like, designed for advertising purposes are assembled in two adjacent chambers with means for conveying the cards one at a time from one chamber to the other so as to bring the cards successively into view for advertising purposes. 1

lnithese devices, it is designedto keep each chamber completely filled with the cards in the form of packs, the rear card of one pack being moved to the rear of the adjacent pack by intermittent motion, the front card of the last named pack being conveyed to the front side of the opposite pack.

Means are provided by which thebody of,

each pack is moved along to make room for the newly arriving cards and means are also provided for an open space where each card as it comes into position can be seen from the outside, remaining long enough in the displaying space for purposes of advertising.

The object of my invention is to construct a machine of this general character and a further object is to provide an illuminating chamber between the two card-holding chambers whereby the card may be illuminated or may, if desired, be projected at a distance and thrown upon a screen.

My invention is illustrated in the accompanying drawing in which a machine is shown with three adjacent chambers, the central chamber being an illuminating chamber for the more conspicuous display of the cards.

Referring to the drawings Fig. 1 shows an end elevation of my device,

Fig. 2 is a front elevation with one ofthe cards displayed 'in the intermediate or illuminated chamber,

Fig. 3 shows a" vertical section taken on the line 3-3 of Fig. 2 looking toward the right,

Fig. 4 is-a section taken on the line 4--4L of F 3,

Fig. 5 is a section taken on the line 5-5 of Fig; 3,

. Fig. 6 is a detail section taken on the line 66 of Fig. 7,

Fig. 7 is a detail section taken on the line 7-7 of Fig. 6,

Fig. 8 is a diagrammatic view taken-on one end of the machine showing the sectional gear which effects the intermittent motion in one position,

Fig. 9 is a like viewv of the same with the intermittent gear and the adjacent gears in the opposite position to that shown in Fig.

8, that is, with the sectional gear turned a little less than one-half revolution and,

Fig. 10 is a front elevation of a portion of the gearing shown in Fig. 2 with certain parts broken away and with arrows to indicate the reverse motions of the gears.

Referring to the drawings, like letters of reference indicate like parts in all the fig ures.

The operative mechanism is a casing of which 1, 2 and 3 are upright plates connected at the top by the top plate a, plate 1 forming one end of the machine. 90 An upright plate 1 forms the back of the machine. A horizontal plate 5 near the bottom of the machine and a horizontal plate 6 at the upper portion of the machine divides the easing into a lower chamber 7, an upper chamber 8 and an intermediate chamber 9. The forward portion of the intermediate contained in chamber is cut away or left open so that a card located in the front portion of the intermediate chamber can be plainly seen from the front as illustrated in Fig. 2. The cards or display plates 10 are contained in the upper and the lower chambers and are conveyed back and forth between the two, passing downward in the front portion of the intermediate chamber and upward in its rear portion. As here shown, the cards in passing between the upper and lower chambers are made to pause long enough to be shown for advertising purposes. 109

The cards are just enough in number to keep both an upper and lower chamber completely filled so that each time a card is added to either one of the chambers a corresponding card is removed, thus keeping both chambers completely filled at all times. The cards in the lower chamber rest on their edges on the partition 5 and a pair of elliptical springs 11 are secured to the front side of the casing press- 110 ing normally inward against the faces ofthe cards 10 near the ends and tending to press them back toward the rear and hold them firmly in such position. The cards in the upper chamber (3 are held in position by elliptical springs 12 which tend to force the body of cards forward to the front portion of the chamber.

The cards are moved one at a. time from the front portion of the chamber 8 down to the front portion or open space in. the intermediate chamber 9' ward part of the chamber? sliding in between the springs 11 and the'forward plate 10 in the lower chamber.

The rear card 10 in the lower chamber 7 is moved upward through the rear portion ofthe chamber 9 to' lO 'and delivered between the springs 12 and therear'card in the upper chamberS at 10 Thus, as a card isadded to the front portion of the lower chamber," theentirebody of the cards is forced backward and each time a card is'added to the upper chamber, the body of the cards is moved forward 'the thickness of a single card so as to keep a continual line of cards moving downward in front and upward in the rear and passing from front to rear in the lower chamber and from the rear to the front in the upper chamber. 7

As here shown, the cards are moved from the front play space in front of the central chamber by a reciprocating rack 13 engaged by a rack gear 16 securedito a shaft 17 "which extends from one end of the casing. to the other being journajlled in the plates 1 and 2. Suitable guides 17 (see Figs. 4, 6 and 7) are-provided in which the rack reciprocates. Two racks 16 both alike are used one at each end of the machine and means are provided so that each card will be seized by the two racks, one at each end. For this purpose, each rack has a hook 1st at its upper end which is adapted to hook over the upper edge of the card and force it downward. The forward position of the forward card of those in the upper chamber is just forward of the edge of the partitionfi so that it is in position to be drawn directly downward into the intermediate chamber and thence into the lower chamber. l

The function of the rack 18 is not only to draw the front card downward from the.

upper chamber but also topush downward a. corresponding card as 10 lodged inxthe intermediate chamber whereit pauses to be exhibited. This motion is effected by a projection. 15 on the lower end of .the rack 13. Upon the descent card 10 is pushed into the lower chamber between the sprin s 11 and the front card in the lower chamber indicated as 10.

The rear card in the lower chamber indicated by 10 is moved to the upper chamber, passing through the intermediate chamber it also hasa projection 23 and thence to the forof the upper chamber 8 to the dis of. the rack 13., the

wi th relation to move downward by a rack 21 which reaches from the lower end of the lower chamber to the lower end. of the upper chamber and is constructed in a similar manner to the rack 13 except that it has a. blank portion on the lower end. The rack2l.has on its inside surface at the lower end a book 21 for lifting the card 10 and for pushing another card as 10 from the half-way position in the intermediate chamber up into the rear position inthe upper chamber as indicated at 10 The rack 21 is engaged by a rack gear mounted 011 a shaft '22 which is a duplicate of the shaft 17 except that'wit extends through an'd is journall'ed inthe end plate 3.

The working mechanism shown. in Fig. 3 is duplicated on the two ends of the machine, that is, thereare'two racl'rs 13 one at each end'of the machine and two gears 16 on the two ends of the shaftfilr', each of the gears engaging one of the racks 13.

Thus, the two gears 16 lift and lower the two racks 18 at exactly the same time. and with the same motion.

On the other hand, the two racks '21are lifted and lowered by the two gears 25 on shaft 22 with exactly the opposite motion given to the .racks13, that is, when the racks 13 are coming down, the racks 21 are going up and so 011 vice versa Illuminating means as an electric light 6O with'a reflector Glare provided whereby intermediate chamber 1 the interior of the may be lighted up so that the advertising cards if they are transparent will show readily with a, brilliantly lighted background when other means maybe provided for illuminat ing the advertising cards as they are brought to rest in the intermediate chamber. The advertising cards used in my machine may be of any desired material as cardboard, metal, celluloid, and they may be transparent or opaque. r

Means are provided by which the two rack gears lti' and 25 are made to rotate in the same direction.

This is accomplished by connecting the ,gears'lE-l and d9 by an intermediate. gear (seeFigsQ 8 and 9) journalled at a point between the two shafts 17 and .22, the gear 49 engaging one side of the intermediate gear 70 and the gear 19 engaging the opposite .side (see F ig.1 1). It will .thus be seen that the rotation of theg'ear 16 which moves the rack 13 in one :directon will r0 tate the gear 25 and a raclr21 will be moved in an opposite direction to the rack 13 owing to the position of the racks 18 and 21 the saidgears. hen one of the racks moves upward the other will and vice versa. Means are provided for reversing: both the motions of the two racks at fixed interlocked, at from the front or ltd) sition in the intermediate chamber,

\als so th tione will move fronii its upper to its lower position, nn in that post tion li;-.ed interval of time andwill' then return to its upper position.

Asherein shown, each rack moves from its upper or lower position to its central pothence back to its first position. In other words, eachrack moves its length either up or down as the case may be, makes a pause and then moves back to its normal position.

The pause made at the end of each movement is sufficiently long for advertising pur poses and for displaying the cards in the open space in the intermediate chamber.

The reversing mechanism by which both the gears 16 and 25 are reversed is efiected by relatively large sectional gear 50 having a comparatively short gear section 51, the teeth of which extend beyond the blank portion 51 of the gear section 51. The sectional gear 50 (see Figs S and 9) is journalled on the plate 2 and between the shaft 17 and the shaft 22. The short gear section 51 engages the pinion 52 (see Fig. 2) on the shaft 22 whereby direct motion is transmitted from the sectional gear 50 to the shaft 22, raising and lowering the rack 21 by means of the intermediate gear 7 O and raising and lowering the rack 13 in the opposite direction as already explained.

The reverse motion is effected by the engagement of the geared section 51 with a pinion 17 which is the counterpart of the pinion 52 on the opposite side of the machine. The pinion 17 is journalled on a short stud 41-6 and secured to a sleeve on the end of which is a gear 18 in engagement with a similar gear 49 on the shaft 17. (See Fig. 2.) r

The pinion 47 is located on the opposite side of the gear 50 of the pinion 52 and as they both mesh with the gear 50 they will rotate in the same direction. The shafts 17 and 22 are rotated in reverse directions by reason of the gear 18 being interposed between the gears 50 and 25 and there being no gear interposed between the gears 50 and 52.

Thus, when the gear 50 in its rotation engages the pinion 52, the rack gears and the racks move in one direction and after the toothed section 51 reaches the other side of the gear 50 and comes into engagement with the pinion 4:? the opposite rotation is effected and both the gears 16 and 25 and the corresponding racks 13 and 21 reverse their direction. p

Thus, the rack moves downward its full length, pauses until the toothed section 51 moves around to engage the pinion 52 or 47 as the case may be. The motions are there reversed and the rack returns to its original position and hooks on the upper edge of the next card. The movements of the rack 21 reverse of Movement on the opposite side are just the the movements of the rack 13.

is imparted to the train of gears by a suitable motor 10 belted to a pulley 41. the same shaftwith the pulley 41 is a pinion 42-which engages a gear 43 on the hollow shaft 44 (see Fig. 10) on the inner end of which is a gear 15. The gear 45 engages a gear 46 (see Fig.1) on the shaft 80 upon which is the pinion S1 engaging the gear 53 rigidly connected with the sectional gear 50. The gear as stated acts to rotate the two shafts 17 and 22 and their connecting gears which act to reciprocate the racks 13 and 21.

A machine such as I have described is an eflicient device not only for advertising but it may be used with advantage for display ing the names of streets or railroad stations for the benefit of the passengers in trolley or railway cars.

I claim 1. In an advertising device the combination of an upper chamber and a lower chamber, both containing a pack of display cards, a middle chamber between the two, a reciprocating rack for conveying the cards one at a time from the upper chamber to the middle chamber and thence to the lower chamber on one side of the device, a reciprocating rack for conveying one at a time from the lower chamber to the middle chamber and thence to the upper chamber on the opposite side of the device, a rack gear for each rack, gearing connected with the rack gears for simultaneously rotating the same and for reversing the movement of the rack gears at intervals, including a sectional gear having a portion arranged to be carried into and out of mesh with the said gearing intermittently, and means for continuously rotating the sectional gear in one direction.

2. In an advertising device, the combination of an upper chamber and a lower chamber, both containing a pack of display cards, a middle chamber between the two, a reciprocating rack for conveying the cards one at a time from the upper chamber to the middle chamber and thence to the lower cham ber on one side of the device, a reciprocating rack for conveying one at a time from the lower chamber to the middle chamber and thence to the upper chamber on the opposite side of the device, a rack gear for each rack, a sectional gear continuously rotating in one direction, gears spaced apart and connected with the rack gears and intermittently engaged by the sectional gear for rotating the rack gears simultaneously and for reversing the rotation of the same at intervals to reciprocate the racks, and an intermediate gear meshing with the said rack gears.

3. In an advertising device the combination of an upper chamber and a lower chamber, both containing a pack of display cards, a middle chamber between On M the two, a reciprocating rack forv conveying the cards one at a time fromethe upper chamber-to the middle 'chamber I and thence to the lower chamber on "one. side of the device, a reciprocating raekhforeonveying one at a time fromcthe lower'ehamher to the-middle chamberand thence to the upper chamber on the opposite side of the devlce, a rack gear for'eaeh-rack, an intermediate gear meshing with'the rack gears for causing the same to simultaneously rotate, a sectionalgear continuously rotatin in one direction and separate 'gears' space apart andrconnected with the rack gears and arrangedto be intermittentlyengaged by the If) sectional gear for reversing the rotation of the rack gears.
